Component Description

INFOID:0000000006257067

Inverter Unit

INFOID:0000000006257068

The inverter unit converts an applied power supply voltage (approximately DC 12 V) to AC 120 V and outputs
the converted voltage.

AC120 V Outlet Main Switch

INFOID:0000000006257069

The operation of the switch enables the inverter unit to activate/inactivate and turn ON/OFF AC 120 V output.

AC120 V Outlet

INFOID:0000000006257070

The AC 120 V outlet allows using AC 120 V converted in the inverter unit as an outlet.

SYSTEM DESCRIPTION

• When turning ON the AC 120 V outlet main switch with the ignition switch ON, the indicator turns ON and the

inverter unit is activated.

• The inverter unit converts power supply voltage to AC 120 V and outputs the converted voltage to the AC

120 V outlet two seconds after the AC 120 V outlet main switch is turned ON.

Fail-safe

INFOID:0000000006257269

When a malfunction listed below occurs, the inverter unit turns OFF the AC 120 V outlet main switch indicator
and stops the output by operating the fail-safe.

JSMIA0295GB

Malfunction item

Fail-safe condition

Fail-safe cancellation condition

Inverter unit is overheat-
ed

When the inverter unit is overheated, the output 
stops to protect the inverter unit.

After the inverter unit temperature is lowered, the 
AC 120 V outlet main switch ON 

 OFF 

 ON op-

eration allows normal return.

Inverter unit power sup-
ply voltage is 11.5 V or 
less

When inverter unit input voltage is lowered, the out-
put stops to protect the battery from running out.

Automatic normal return when inverter unit power 
supply voltage reaches 11.5 V - 16 V. 

Inverter unit power sup-
ply voltage is 16 V - 18 V

When inverter unit input voltage reaches 16 V - 18 V, 
the output stops to protect the inverter unit.

Automatic normal return when inverter unit power 
supply voltage reaches 11.5 V - 16 V. 

Inverter unit power sup-
ply voltage is 18 V or 
more

When inverter unit input voltage reaches 18 V or 
more, the output stops to protect the inverter unit.

After the inverter unit power supply voltage reaches 
11.5 V - 16 V, the AC 120 V outlet main switch ON 

 OFF 

 ON operation allows normal return.

Inverter unit output cur-
rent is 2.8 A or more

When inverter unit output current reaches 2.8 A or 
more, the output stops to prevent over current. (e.g. 
connecting an electric appliance exceeding rated 
output)

Automatic normal return when inverter output cur-
rent reaches 2.8 A.

Inverter unit output signal 
(AC 120 V output signal) 
is shorted

When inverter unit output signal is shorted, the out-
put stops.

After recovering from inverter unit output signal 
short, the AC 120 V outlet main switch ON 

 OFF 

 ON operation allows normal return.

CAUTION:

• To measure AC 120 V output signal, always use the circuit tester or oscilloscope AC range.

Never allow the probes to contact each other.

• Because of modified sine wave output of the AC 120 V output signal, voltage cannot be measured

accurately without using a circuit tester that can measure true RMS (root mean square).
